The next meeting of the National Seminar on Probability and Statistics will be held on .June 19, 2019 (Wednesday), at 2.00 p.m., in Eoom 403 of the Institute of Mathematics and Informatics, BAS. A talk on A decomposable multi-type Bellman-Harris branching process with mutations. Application in modeling of cancer evolution will be delivered by Kaloyan Vitanov (PhD student at Sofia University). Everybody is invited. Abstract: A prominent feature of biological systems is their capacity to adapt and mutation is a key mechanism for achieving adaptation. As a continuation of [3] we propose a decomposable multi-type Bellman-Harris branching process, which incorporates a possibility for mutation. Metastasis, the spread of cancer cells from a primary tumour to secondary location(s) in the human organism, is the ultimate [...]
